DRAINAGE DEVICE FOR ROOF GUTTERS AND THE LIKE Filed May 51. 1929 5Sheets-Sheet 5 INVENTOR ATTORNEY Patented June 23, 1931 UNITED STATESPATENT OFFICE ROBERT MCKEE, OF PHILADELPHIA, PENNSYLVAN DRAINAGE DEVICEFOR ROOF GUTTERS THE LIKE Application med May 31,

It is well known that roof gutters clog up, due to leaves and otherforeign matter, thereby allowin no way for the rain water to p drainoff. ometimes thestoppage is caused by rags, paper and any foreignmaterial that will not pass through the drain pipe leading from thegutter.

Therefore the present invention relates to an improved drain device tobe inserted in the drain pipe and located between the opposite walls ofthe roof gutter.

The purpose of the invention is to provide a cage comprising a multipleof stays, arranged in cylindrical formation, withtheir lower ends freeand unattached, therefore yieldable, to permit the drain device to beinserted in the drain pipe, hence. adapted to be sup orted in differentpositions, slightly above t e margin of the outlet end of the pipe,

' in order to allow the water to drain off. The

stays prevent foreign matter such as leaves and the like from passingthrough.

Another purpose is to provide an improved drain device having an outerabutment ring, with a plurality of inner rings in spaced positions andgraduated, in order to carry ofl the rain water. at different levels inthe gutter, the stays of the cage above the abutment ring acting toprevent the passage of foreign matter through the drain pipe.

' A still further purpose is to provide an apex cap at the top of thecage for retaining the radial bent ends of the stays in position, theapex cap in one instance, as shown in the drawings, having a dependingcylindrical wall disposed in spaced concentric position with theuppermost ring member, so that should small particles of refuse stop upthe spaces between the .various concentric 1929.

trically spaced rings, so th be fastened to each other.

It is to be understood that the particulars herein given are in no waylimitative, and that while still keeping within the scope of theinvention, any desired modification of details and proportions may bemade in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to behereinafter set forth, shown in the drawings and claimed.

Figure 12 is a. cross sectional View on line 1212 of Figure 11.

Referring to the drawings, 1 identifies a pit-ch roof, 2 the gutter, 3the cornice and 4 the drain pipe, while in Figure 2 the roof 5 isapproximately flat, which may be either tin or slag. Though there aretwo forms of roofs, the roof gutter in both instances are identified bythe same numeral, and so is the drain pipe.

Adapted to be arranged in the drain pipe is a drain device 6, which inevery instance comprises a cage 7 made up of stays 8, except ing inFigure 10 where the cage merely extends halfway of the device. The stays8 are constructed of sheet metal, that is in strips. For instance eachstrip is bent longitudinally upon itself, the'bent portions being foldedover to insure rigidity, and the stays are secured to a base abutmentring 9, which is also made of sheet metal, in a strip and bentlongitudinally upon itself, as shown in the sectional views. The crosssectional construction of the stays is disclosed in the cross sectionalviews 5 and 7.

The stays extend above and below the abutment base ring, the lowerportions acting to engage within the drain pipe, the drain device beingcapable of adjustment to different heights, so that the drainage of rainwater may take place below the abutment ring. However the abutment ringmay rest on the bottom of the roof gutter as shown in Figure 2.

Arranged within the cage is a plurality of rin 10, which are concentricwith each other and suitably spaced. The rings are disposed in graduallyincreasing heights, so as to appear in conical formation within thecage, the different heights being for the purpose of draining off rainwater at different levels. It is obvious that when the drain device isfirst applied to a drain pipe therain water will drain off at all timesat a lower level. However should the first space become clogged, thenthe second space between certain of the rings will carry the rain wateroff, and should the second space become clogged, the third space willcarry off the water and so on throughout the height of the cone.

In order to support the innermost rings 10, they are provided withlateral lugs 11, which are struck up from the rings themselves, as shownat 12. Theselugs are in turn soldered or electrically welded to adjacentrings, as shown clearly in Figures 4, 5 and 7. However the larger rings13 at the bottom are fastened to the inner faces of the stays by anywell known means, for instance soldering or electrically spot welded to.the inner faces of the stays, at a point adjacent the abutment ring 9.

The upper parts of the stays are bent at 14L and are radially inclinedtothe cage, and as in Figures 3 and a the terminals of the inwardly bentportions 15 are fastened by soldering or electrically spot welding at16, to an apex cap 17.

As in Figures 1, 3 and 4 the apex cap 17 is in turn fastened bysoldering or spot welding to a cylindrical Wall 18, which depends intoan adjacent ring.

In Figures 2, 6, 8, 9 and 11 the inwardly turned parts 15 of the staysare soldered or spot welded between inner and outer apex caps 19 and 20,therefore further insuring rigidity.

The lower parts of the stays are more or less yieldable, so as to engagewithin the drain pipe frictionally, in order to hold the cage indifferent positions.

Also in Figures 6, 8, 9, 10 and ll-the several innermost rings vary innumber, which is more or less a matter of choice as tohow many rings thepresent type of drain device may possess.

In Figure 10 the construction of the drain device is more or lessmodified as compared with the other drain devices, in that the staysextend down from the larger base ring 21, while the upper part of thedrain device is entirely opened, that is on the sides adjacent thevarious rings forming the conical part of the drain device.

The upper part of the drain device in Figure .10 has the apex cap 22supported on the smaller upper ring 23 by means of supporting arms 24:.The supporting arms are soldered or spot welded or otherwise fastened tothe ring 23.

The various lugs for mounting and supporting the several rings inposition are struck up from the rings at various locations, so that allthe lugs will not align in a radial direction.

In Figures 1 to 12 inclusive the various inner rings or members; thatis, whether circular, rectangular or otherwise formed, are arranged atgradually increasing heights and are operatively supported within thecage and spaced in conformity with each other. The spaces between theplurality of rings or members constitute passages for rain water.

As previously stated the rain water will drain oil at different levels,accordingrasthe spaces between the rings may clog up.

The invention having been set forth, what is claimed is:

1. A drain device for roof gutters and drain pipes, comprising a cagehaving depending yield able-stays, which engage within the drain pipe,said cage having an apexcap supported at the top of the device, aplurality of cylindrical concentricspaced rings operatively supportedwithin the cage at gradually increasing heights, thereby arranging therings in conical formation.
